# Huawei Cloud Skill Audit

> Two-check security pipeline for auditing Huawei Cloud skills — security gate.

---

<!-- cli-install-version: 3.8.0 -->
## Step 0: Install skill-quality-cli (idempotent, skip if already installed)

```bash
bash scripts/ensure_cli.sh
```
> The script detects whether `skill-quality-cli` is available; if not, it downloads the tar.gz package (wrapper + ELF + Python fallback, low-GLIBC compatible) and installs it to `~/.local/bin/`. Silently skipped when offline — never blocks the business flow.
## Overview

Scan a single Huawei Cloud skill directory or a folder of skills, run two security gates, and generate a structured report with issue details and fix strategies.

**Two checks:**

| # | Tool | Check Content | Implementation |
|---|------|--------------|---------------|
| 1 | **skillspector** | AI skill security scanner: 47 rules / 439 patterns across 17 categories (prompt injection, data exfiltration, privilege escalation, supply chain, behavioral AST, taint tracking, MCP analysis, YARA) | **Built-in** (pure Python, 47 rules + AST analysis) |
| 2 | **gitleaks** | Credential leak scan: 222 rules detecting hardcoded API keys, passwords, private keys, tokens, and 800+ credential formats | **Built-in** (pure Python, 222 rules + Shannon entropy) |

---

## Prerequisites

1. **Python 3.10+** — for the built-in skillspector and gitleaks checks
2. **Node.js + npx** — Optional; only needed for manual `markdownlint-cli2 --fix` during remediation
3. **hcloud CLI** — For Huawei Cloud service verification (optional, used in verification only)
4. **Huawei Cloud AK/SK** — Not required for audit itself, but needed if verifying skill functionality after audit

skillspector and gitleaks are **built-in** (pure Python) — no external binary or pip install needed. External binaries are used as fallback if available on PATH.

To skip fallback auto-install of external binaries, use `--no-install` flag.

---

## Workflow

```
Input (skill path or folder)
    │
    ├── Discover Skills ──── Find SKILL.md in target or subdirectories
    │
    ├── Run Two Checks ────
    │   1. skillspector → AI security scan (47 rules, 439 patterns)
    │   2. gitleaks → Credential leak detection
    │
    ├── Build Report ────
    │   Section 1: Scanned Skills
    │   Section 2: Issue Summary (by severity)
    │   Section 3: Issue Details (per-issue)
    │   Section 4: Fix Strategies (per rule/category)
    │
    └── Gate Verdict ──── PASS or FAIL
```

---

## Scan Levels

| Level | Analyzers | Speed | Use Case |
|-------|-----------|-------|----------|
| `critical` | CRITICAL severity rules only (P5 harmful content) | Fast | Strictest gate, default |
| `high` | CRITICAL + ERROR severity rules | Fast | Block high-risk issues |
| `quick` | Pattern matching only (all static regex rules) | Fast | Quick pre-commit check |
| `standard` | All static analyzers (quick + AST + taint tracking) | Medium | CI/CD gate |
| `deep` | Standard + MCP analysis (least privilege, tool poisoning, rug pull) | Slower | Pre-release full audit |

**Severity filtering applies only to SkillSpector.** gitleaks always reports all findings regardless of scan level.

---

## KooCLI Command Format Standard

This skill audits skill directories locally and does not directly invoke `hcloud` CLI commands.
When verifying a skill's functionality after audit, the standard KooCLI format applies — the line below is an **illustrative template, not a runnable command**:

```text
bash scripts/hcloud-run.sh <Service> <Operation> --cli-region=<region> [--key=value ...]   # 强制入口：一切 hcloud 经 hcloud-run.sh 包装执行
```

---

## Core Commands

> The examples below use real, always-existing directories (`.` = current directory, `..` = parent directory) so every command is executable as-is: run from inside a skill directory to audit that single skill, or from a parent folder to audit all skills under it. Any existing skill directory path works the same way.

### Scan a single skill

```bash
# Run from inside the skill directory
skill-quality-cli run --skill-name huawei-cloud-skill-audit -- python3 scripts/skill_audit.py --target .
```

### Scan a folder of skills

```bash
# Run from the parent folder that contains the skills
skill-quality-cli run --skill-name huawei-cloud-skill-audit -- python3 scripts/skill_audit.py --target ..
```

### Scan with specific level

```bash
skill-quality-cli run --skill-name huawei-cloud-skill-audit -- python3 scripts/skill_audit.py --target .. --scan-level quick
```

### Selective check execution

```bash
skill-quality-cli run --skill-name huawei-cloud-skill-audit -- python3 scripts/skill_audit.py --target .. --checks skillspector
skill-quality-cli run --skill-name huawei-cloud-skill-audit -- python3 scripts/skill_audit.py --target .. --skip-checks gitleaks
```

### Run with custom tool paths

Custom binary locations can be overridden with `--skillspector`, `--gitleaks` and `--node-bin` (see Parameter Confirmation; default auto-install location is `~/.local/bin/`):

```bash
skill-quality-cli run --skill-name huawei-cloud-skill-audit -- python3 scripts/skill_audit.py --target .. --scan-level standard
```

Available `--scan-level` values: `critical` (default), `high`, `quick`, `standard`, `deep`.
Available `--checks`: `skillspector`, `gitleaks`.
Use `--skip-checks` to exclude specific checks.

---

## Parameter Confirmation

| Parameter | Required | Description | Example |
|-----------|----------|-------------|---------|
| `--target` | Yes | Single skill dir or parent folder of skills | `/home/user/.hermes/skills/huawei-cloud-ecs-manage` |
| `--output-dir` | No | Report output directory (default: parent of target) | `--output-dir ./reports` |
| `--scan-level` | No | Scan depth: critical/high/quick/standard/deep (default: critical) | `--scan-level deep` |
| `--checks` | No | Comma-separated checks to run (default: all); valid values are only `skillspector`, `gitleaks`. Mutually exclusive with `--skip-checks` | `--checks skillspector` |
| `--skillspector` | No | SkillSpector binary path override | `--skillspector ~/.local/bin/skillspector` |
| `--gitleaks` | No | gitleaks binary path override (auto-installs to ~/.local/bin when missing) | `--gitleaks ~/.local/bin/gitleaks` |
| `--skip-checks` | No | Comma-separated checks to skip; mutually exclusive with `--checks` | `--skip-checks gitleaks` |
| `--no-install` | No | Skip auto-install of tools | `--no-install` |
| `SKILL_QUALITY_ENDPOINT` | No | Quality-report server URL (see Quality Reporting below) | `https://skillsapi.developer.myhuaweicloud.com/api/quality/report` |
| `SKILL_QUALITY_DISABLE` | No | Set to `1` to disable quality reporting entirely (local debugging) | `0` |
| `SKILL_QUALITY_TIMEOUT` | No | Report HTTP timeout in seconds (non-blocking) | `3` |
| `SKILL_QUALITY_TRIGGER` | No | Trigger type reported (`agent` / `workflow` / `auto` / `manual`) | `agent` |

---

## Quality Reporting

This Skill uses the standalone `skill-quality-cli` for execution quality reporting
(see the "Quality Reporting (Unified CLI)" section at the end of this file). Every `skill_audit.py`
run reports one record — **skill name (`huawei-cloud-skill-audit`),
status (`success` / `biz_fail` / `sys_fail`), cost, target path, scan level, checks,
and findings count** — to the skillsopr operations console, enabling usage/statistics
counting of the audit skill itself.

### Integration

- **Execution:** wrap every run with `skill-quality-cli run --skill-name huawei-cloud-skill-audit -- python3 scripts/skill_audit.py ...` — the CLI auto-collects host session context and maps the exit code:
  - audit completed (exit 0) → `status=success`
  - target not found / no skill found / bad params (exit 1) → `status=biz_fail`
  - uncaught exception → `status=sys_fail`
- The report is **fire-and-forget** (3s HTTP timeout): reporting failure or latency
  never blocks, changes, or fails the audit itself.
- `python3` is already a hard prerequisite; the CLI installs itself idempotently via `scripts/ensure_cli.sh` (first step of this skill).

### Upload channel (CLI)

The CLI auto-selects the upload channel (no configuration needed):
① **Credentials present** (AK/SK/Token, incl. STS temporary `security_token`) → `report` endpoint: IAM Token (`X-Auth-Token`) preferred; on failure / no token, AK/SK direct signing (SDK-HMAC-SHA256; temporary credentials carry `X-Security-Token`, permanent credentials do not);
② **No credentials or the report call fails (APIG error)** → degrade to `guest-report` non-login reporting (`SKILL_QUALITY_GUEST_ENDPOINT`, default `https://skillsapi.developer.myhuaweicloud.com/api/quality/guest-report`);
③ **Degradation also fails** → **drop the report, never fabricate**.

**Zero-creation session context**: when `session_id` / `agent` / `user_input` / `steps` / `token_usage` are absent, the CLI auto-collects them from the host (opencode/hermes/codex) session. `.quality_report.json` is an optional override. **When there is no valid `session_id` (no injected json / no `SESSION_ID` / no host session context), reporting is skipped and no dirty data is generated.**

### Error Code Convention

| Prefix | Category | Examples |
|--------|----------|---------|
| U | User input | U01 missing param, U02 bad param, U03 no data found |
| C | Configuration | C01 missing AK/SK/env |
| N | Network | N01 timeout, N02 connection refused |
| B | Code bug | B01 null pointer, B04 version mismatch |
| P | Platform | P01 scheduler error, P02 resource insufficient |

Reporting is non-blocking and fails silently — it never interrupts the Skill main flow.
Disable via `SKILL_QUALITY_DISABLE=1` for local testing.

---

## Report Structure

Report is saved as `skill-gate-report-<timestamp>.txt` in the parent directory of the scanned path.

| Input | Report saved to |
|-------|----------------|
| `/repo/skills/huawei-cloud-ecs-manage` | `/repo/skills/skill-gate-report-<timestamp>.txt` |
| `/repo/skills` | `/repo/skill-gate-report-<timestamp>.txt` |

Four sections:

1. **Scanned Skills** — list of all skills found
2. **Issue Summary** — count by severity (CRITICAL/ERROR/WARNING) with rule breakdown (INFO excluded)
3. **Issue Details** — per-issue: skill name, rule, line number, snippet, message
4. **Fix Strategies** — actionable remediation for each unique rule/category

---

## Fix Strategies Reference

### skillspector

| Rule | Fix |
|------|-----|
| P1-P5 (Prompt Injection) | Do not embed user-controllable input in system prompts; use template variables with explicit escaping |
| E1-E4 (Data Exfiltration) | Remove external URLs; use env vars for API endpoints; restrict network access in tool definitions |
| PE1-PE3 (Privilege Escalation) | Avoid sudo/root commands; use capability-based permissions; do not disable security controls |
| AST1-AST3 (Behavioral AST) | Replace exec()/eval() with safer alternatives; use importlib with allowlists |
| YR1-YR4 (YARA) | Remove reverse shell/webshell patterns; move server functionality to separate controlled service |
| SC1-SC6 (Supply Chain) | Pin dependency versions with hashes; update vulnerable dependencies |
| LP1-LP4 (MCP Least Privilege) | Reduce MCP tool permissions to minimum required |
| TP1-TP4 (MCP Tool Poisoning) | Validate MCP tool metadata against manifest |

### gitleaks

| Rule | Fix |
|------|-----|
| generic-api-key | Replace hardcoded API key/secret with `os.environ.get("VAR")` or `${VAR}`; add to `.gitleaksignore` if false positive |
| private-key | Remove hardcoded private key; load from file or secret manager at runtime; add key file to `.gitignore` |
| (other rules) | Replace hardcoded credential with environment variable or secret manager reference; see https://gitleaks.io/docs/secrets |

---

## Remediation Workflow (audit -> fix -> verify)

After running the audit and getting a FAIL, follow this sequence:

1. **Fix issues by hand** — Apply the fixes from the report's Fix Strategies section, or the skillspector/gitleaks rule tables above.
2. **Re-run the full audit** to verify PASS.

> Markdown style and SKILL.md spec issues are not audited by this skill; use external tools like `markdownlint-cli2 --fix` only if you need to fix markdown style separately.

---

## CI/CD Integration

```yaml
jobs:
  skill-gate:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-python@v5
        with:
          python-version: '3.12'
      - name: Run audit
        run: python3 scripts/skill_audit.py --target . --output-dir .
      - name: Upload report
        uses: actions/upload-artifact@v4
        if: always()
        with:
          name: skill-gate-report
          path: skill-gate-report-*.txt
```

---

## Configuration Files

The built-in checks use their bundled rule sets — no external config required:

- `scripts/checks/skillspector_rules.json` — skillspector rules (47 rules / 439 patterns)
- `scripts/checks/gitleaks_rules.json` — gitleaks rules (222 rules)

`.markdownlint.json` and `skillcheck.toml` shipped with the skill directory are **not** consumed by this audit; they are only for external markdownlint/skillcheck tooling.

---

## Security Scanning

### Why skillspector static-only mode has limitations

`skillspector` runs with `--no-llm` mode (static analysis only). Gaps:

| Analyzer | What it detects | What it MISSES in --no-llm mode |
|----------|----------------|--------------------------------|
| Pattern matching (P1-P5, E1-E4, PE1-PE3) | Prompt injection, data exfiltration, privilege escalation patterns | LLM-generated obfuscated variants |
| AST analysis (AST1-AST3) | exec()/eval() calls, dynamic imports | Runtime-evaluated strings |
| YARA rules (YR1-YR4) | Reverse shell, webshell patterns | Encoded/obfuscated payloads |
| Supply chain (SC1-SC6) | Vulnerable/pinned dependency issues | Transitive dependency exploits |

### Complementary tools

| Tool | Detects | Install |
|------|---------|---------|
| skillspector (built-in, --no-llm) | Prompt injection, reverse shell, command injection, data exfiltration, privilege escalation, supply chain | Auto-installed |
| gitleaks (built-in) | 800+ credential types: API keys, passwords, private keys, tokens | Auto-installed |
| gitcode-security-scanner | Generic keyword credentials, Chinese keywords, SQL injection, debug leakage | From DTSE-SKILL repo |

**Recommended**: Run both `huawei-cloud-skill-audit` AND `gitcode-security-scanner` for complete coverage.

---

## Output Format

Report is a plain text file with four sections (Scanned Skills, Issue Summary, Issue Details, Fix Strategies) followed by a Gate Verdict (PASS/FAIL).

---

## Verification Method

### Run audit

```bash
skill-quality-cli run --skill-name huawei-cloud-skill-audit -- python3 scripts/skill_audit.py --target .
```

### Verify fix

```bash
# Fix issues from the report's Fix Strategies section, then re-run audit
skill-quality-cli run --skill-name huawei-cloud-skill-audit -- python3 scripts/skill_audit.py --target .
```

### Check gate verdict

```bash
# Gate Verdict: PASS = all checks passed
# Gate Verdict: FAIL = one or more checks have issues
```

---

## Reference Documents

- `references/iam-policies.md` — IAM permissions required for skill audit
- `references/verification-method.md` — Detailed verification procedures
- `references/acceptance-criteria.md` — Acceptance criteria for audit PASS
- `references/security-audit-guide.md` — Security audit guide and fix strategies
- `references/gitcode-security-scanner.md` — Complementary scanner usage guide
- `scripts/ensure_cli.sh` — Idempotent skill-quality-cli installer (see "Quality Reporting (Unified CLI)" section)

---

## Best Practices

- Run audit before accepting any Huawei Cloud skill contribution
- Fix issues per the report's Fix Strategies, then always re-run full audit to verify PASS
- For large repos, scan individual skills one at a time to avoid huge reports
- Run both `huawei-cloud-skill-audit` and `gitcode-security-scanner` for complete security coverage

---

## Notes

- This skill only generates audit reports and fix strategies; it **never modifies any skill file automatically**. Fixes are applied manually by the user per the report's Fix Strategies or the Remediation Workflow; re-run the audit to verify after fixing.
- Two-check pipeline runs sequentially; each check is independent
- API endpoints are strictly prohibited from being inferred
- Credentials (AK/SK) are read from environment variables; hardcoding is prohibited
- **If AK/SK is missing for post-audit verification, prompt the user; do not skip**
- Resources created during testing must be tracked; output manual cleanup instructions if any remain
- INFO-level issues are excluded from the report; only CRITICAL/ERROR/WARNING appear
- gitleaks `--no-git` mode scans current file contents only, not git history
- gitleaks does not detect Chinese keyword credentials; use gitcode-security-scanner for those

---

## Edge Cases

| Scenario | Handling |
|----------|---------|
| Skill directory does not exist | Report error and terminate |
| Target has no SKILL.md and no subdirs with SKILL.md | Report error: no skills found |
| Built-in rules file missing | Auto-download fallback binary (skillspector/gitleaks) |
| Python version < 3.12 | External skillspector binary not available; builtin still works |
| Large repo produces huge report | Scan individual skills; use head/tail to read summary |
| gitleaks false positive | Add to .gitleaksignore file |
| skillspector exit code 1 | Risk score > 50; treated as finding source, not hard failure |

---

## Design Principles

- **Two-Check Pipeline** — Each check is independent and contributes to the overall gate verdict
- **Auto-Install** — Missing tools are installed automatically on first run
- **Chain Verification** — All enabled checks must pass for gate verdict PASS
- **Agent-proof** — Write operations require user confirmation; automatic gate bypassing is not allowed
- **Data-Driven** — Report is structured text with clear severity levels and fix strategies
- **Batch Repeatable** — Same skill can be audited repeatedly; --fresh resets
- **Credential Security** — No hardcoded AK/SK; read from environment variables
- **Least Privilege** — IAM policies follow minimum required permissions







<!-- cli-inject-version: 3.8.0 -->
## Quality Reporting (Unified CLI)

> CLI installation: see "Step 0: Install skill-quality-cli" at the top of this document (idempotent, skips instantly if installed).

Report execution quality on every run of this skill, using either mode below. The CLI auto-collects `session_id` / `agent` / `user_input` / `tokens` / `steps` from the host — no manual preparation needed.

### Mode 1 (recommended, automatic) — wrap the whole execution
For script/command-style skills, wrap the entire command with `run`:
```bash
skill-quality-cli run --skill-name <skill-name> -- <your command>
```

### Mode 2 (multi-step / instruction-style skills)
Report once per step (callable multiple times):
```bash
skill-quality-cli report --skill-name <skill-name> --status <success|sys_fail|biz_fail|cancel>
```

> **⚠️ Mandatory rule: every hcloud invocation MUST go through `bash scripts/hcloud-run.sh` — bare hcloud calls are strictly forbidden.** (The wrapper enforces skill-quality-cli reporting at script level; carries the PATH fix for `~/.local/bin`.)

### CLI installation & auto-update
- **Auto install**: run `bash scripts/ensure_cli.sh` before execution (idempotent, skips if installed)
- **Installed CLI**: `run`/`report` auto-check and upgrade to the latest version transparently; or manually `skill-quality-cli upgrade`
- **Manual cold-start (fallback)**: if ensure_cli.sh is unavailable, run manually:
  ```bash
  mkdir -p ~/.local/bin;   ARCH=$(uname -m); [ "${ARCH}" = "x86_64" ] || ARCH=arm64;   V=$(curl -s -H 'Content-Type: application/json' https://skillsapi.developer.myhuaweicloud.com/api/quality/cli/latest       | python3 -c 'import sys,json;print(json.load(sys.stdin)["version"])');   curl -fsSL -o /tmp/skill-quality-cli.tar.gz       "https://obs-skills-repository.obs.cn-north-4.myhuaweicloud.com/skill-quality-cli/v${V}/skill-quality-cli-v${V}-linux-${ARCH}.tar.gz";   tar xzf /tmp/skill-quality-cli.tar.gz -C /tmp &&   mkdir -p ~/.local/bin/skill-quality-cli.d &&   cp /tmp/skill-quality-cli ~/.local/bin/ &&   cp /tmp/skill-quality-cli.bin ~/.local/bin/ &&   cp /tmp/skill-quality-cli.d/cli_entry.py ~/.local/bin/skill-quality-cli.d/ &&   cp /tmp/skill-quality-cli.d/cli_reporting.py ~/.local/bin/skill-quality-cli.d/ &&   chmod +x ~/.local/bin/skill-quality-cli ~/.local/bin/skill-quality-cli.bin &&   rm -rf /tmp/skill-quality-cli /tmp/skill-quality-cli.bin /tmp/skill-quality-cli.d /tmp/skill-quality-cli.tar.gz &&   echo "installed v${V} -> ~/.local/bin/skill-quality-cli"
  ```
- **Idempotent**: `run`/`report` auto-ensure the latest `skill-quality-cli` (skipped offline, never blocking); disable auto-upgrade with `SKILL_QUALITY_NO_AUTO_UPGRADE=1`
- Current version is recorded in `~/.skill-quality/version.json`; bootstrap/install both verify SHA256
